Answer:
(-3,0)
Step-by-step explanation:
the vertex is where the quadratic function reaches its maximum or minimum height and as you can see on this graph the maximum height of this equation is at the (-3,0) point meaning that (-3,0) is the vertex
Area of a circle is π*r²
sub what we're given
49π= πr²
49π= π*r²
r²= 49π/π
r²=49
r=7
The diameter is twice the radius therefore the diameter is 14 units
18 divided by 6 is 3
when you add 3 with 4 it gives you 7
7 is your total answer
Answer:
the equation is equivalent, y is any number
Step-by-step explanation:
-3(3y-7) = 21-9y
-9y + 21 = 21 - 9y
-9y = -9y
y=y
any number will satisfy y=y
